Bedside Clock Issues

I am running a BB 9900 with release .540. On my old 9700 running OS 6, I could put the device in bedside mode while charging and the clock would continue to display (though dimly). On my 9900, the screen goes black after a couple minutes. Is there any way to prevent the screen from going black? I like to use it as my bedside clock.

In your clock options, set it to enter bedside mode when charging. Dismiss clock automatic should be checked and I have mine set to restrict to certain hours (10-6). Does it work now? Mine will also go black if it's not seated correctly in the charging pod.
